泰州组露头仅零星见于仪征县小河口地区,广大苏北坳陷内据钻井揭示,除建湖隆起及其它个别地区外,一般均有分布,厚度在30—300米间,最厚达400米。并可划分为两个岩性段,即上部泥岩段和下部砂岩段。其岩性除金湖凹陷和高邮凹陷西北部,以咖啡色、棕灰色、紫红色等一红到底的杂色砂泥岩互层,上下分层不明显外,其它各区的上部泥岩段则多以灰黑色泥岩为主,局部地区在其顶部有厚度不等的杂色泥岩、砂泥岩层;下部砂岩段,以棕灰色、浅灰至灰白色粉砂岩、细砂岩为主,夹少量灰紫色或灰黑色粉砂质泥岩,底部常有厚度不等的砂砾岩或砾岩存在。泰州组中的孢粉及介形类化石
Taizhou group outcrops found only sporadic Yizheng County small mouth area, the vast northern Jiangsu Depression According to drilling revealed, except for Jianhu uplift and other individual areas, are generally distributed, the thickness of 30-300 meters, the maximum thickness of 400 meters . It can be divided into two lithologies, namely the upper mudstone section and the lower sandstone section. The lithology except for the Jinhu depression and the northwestern Gaoyou sag, with brown, brown-gray, purple and other red to the end of variegated sand and mud interbedded layer, the upper and lower stratification is not obvious, the other areas of the upper mudstone are mostly gray Black mudstone dominated some areas in its top with varying thickness of variegated mudstone, sandstone and mudstone; the lower sandstone section, with brown, light gray to grayish white siltstone, fine sandstone, a small amount of gray purple or gray black Silty mudstone, often the bottom of the thickness of conglomerate or conglomerate presence.
